In this paper, FeVO 4 materials were prepared via a facile hydrothermal method under different pHs and were developed as highly efficient biomimetic catalysts for the first time.Different FeVO 4 materials with different crystal structures, morphologies and surface properties showed distinct peroxidase-like activities. Experimental results showed that the products obtained at pH = 4 (FeVO 4 -4) possessed a belt-like nanostructure with a large BET specific surface area and exhibited the best intrinsic peroxidase-like activity compared to other FeVO 4 materials. FeVO 4 -4 nanobelts (NBs) could efficiently catalyze the oxidation of 3,3",5,5"-tetramethylbenzidine (TMB) in the presence of H 2 O 2 to generate a blue oxide. Based on the highly efficient catalytic activity of FeVO 4 -4 NBs, a novel system for optical determination of H 2 O 2 was successfully established, and the detection limit of H 2 O 2 could reach 0.2 μM. FeVO 4 -4 NBs also exhibited excellent selectivity, reproducibility, long-term stability, and easy recovery property. Furthermore, a peroxidase mimetic mechanism of FeVO 4 -4 NBs was proposed based on the active species trapping experiments. This work developed a novel, accessible and highly sensitive system for visual detection of H 2 O 2 , making FeVO 4 -4 NBs a potential biomimetic catalysts in H 2 O 2 detection and biomedical analysis.

In view of its high-yield production and robust stability, the Pt-MoO 3 hybrid nanomaterials could be used as an excellent substitute for HRP.…”

Liquid-phase growth of platinum nanoparticles on molybdenum trioxide nanosheets: an enhanced catalyst with intrinsic peroxidase-like catalytic activity

et al. 2014

A facile method for the synthesis of metal nanostructure-decorated two-dimensional (2D) semiconductor nanosheets was developed. The solution-processable molybdenum trioxide (MoO3) nanosheet was used as a template for direct liquid-phase growth of platinum nanoparticles (Pt NPs) under ambient conditions. Results show that the Pt NPs with sizes of 1-3 nm were uniformly grown on the MoO3 surface. Importantly, the Pt-MoO3 hybrid nanomaterial exhibits an enhanced peroxidase-like catalytic activity compared to the MoO3 nanosheet, Pt NPs, and their physical mixture under the same conditions. As a proof-of-concept application, the Pt-MoO3 hybrid nanomaterial was used as a high-efficiency peroxidase-mimic for ultrasensitive colorimetric detection of glucose in serum samples. This work provides a promising strategy for design and development of biomimetic catalysts by smart assembly of different dimensional nanomaterials.

Synthesis of polyaniline via DNAzyme-catalyzed polymerization of aniline

2014

In this report, a novel method for the synthesis of polyaniline in aqueous medium, based on a Gquadruplex DNAzyme-catalyzed oxidation and polymerization of aniline by hydrogen peroxide in the presence of a polyanionic template, is described. The synthesis is simple and the experimental conditions are mild. The polymerization of aniline is carried out in an acidic aqueous medium with a catalytic amount of the DNAzyme. It was found that aniline polymerization occurs in a pH range from 2.0 to 5.0 with an optimal pH of 3.0. The polymerization kinetics can be described by the classical Michaelis-Menten reaction mechanism. Comparing to the horseradish peroxidase-catalyzed polymerization of aniline, the advantages of using the DNAzyme as the catalyst in the polymerization of aniline are cost-effectiveness and greater tolerance to the acidity of the reaction solution and high concentrations of hydrogen peroxide.
